radiographic techniques of imaging soft tissues

1. SOFT TISSUE RADIOGRAPHY
WADP DARSHANA
RADIOLOGIC TECHNOLOGIST-SRI LANKA

2. What are soft tissues?
Tissues other than bones

3. Why we need special techniques to
demonstrate soft tissues?
• Differential attenuation is less in soft tissues.
• So the subject contrast is less in soft tissues.

4. Difference densities according to
differential attenuations

5. How to change the contrast of
radiographic image?
• By Changing Kvp
• By adding filters

6. Use of normal Kvp
• Air and Fat are low dense and give blackish
appearance than other tissues if we use
normal kvp.

7. Enalarged adenoid is seen in
nomal neck exposures
??????????????

8. Knee effusions seen in normal Kvp

9. lipohaemoathrosis

11. Soft tissue swelling

12. Normal & abnormal kagers fat pad

13. Sub normal kvp in mammo

14. Skull normal exposure vs soft tissue
exposure……….
use profile projections(tangenital)

15. Low kv

16. High kv

17. Need of high kv in Ba enema

18. Use of filters filters

20. Digital technology

21. Conventional vs digital mammo

22. • To demonstrate soft tissues successfully;
special attention must be given to;
-Radiographic contrast
-Image sharpness
-Avoidance of artifacts

23. • ANY QUESTIONS or DISCUSSIONS??
